When the migration tool is run in permissive mode, its visitors try to catch exceptions and continue running. This means that when the visitors make temporary state changes before recursive calls, they have to restore the state inside `finally` blocks. This should hopefully result in slightly saner behavior when running the migration tool in permissive mode.
